8 Instrument Status
The Event Register is read with the command:
STATus:QUEStionable[:EVENt]?
Unlike the Condition Register, the bits in the Event Register remain set
following the condition that occurred. The bits are cleared by reading the
register.
Enable Register
The Enable register specifies which bits in the Event register can generate a
summary bit which is subsequently used to generate a service request.
Bits within the Event Register are enabled with the command:
STATus:QUEStionable:ENABle <enable>
STATus:QUEStionable:ENABle? (query form)
- enable: decimal value corresponding to the binary-weighted sum of the bits
in the register. For example, to enable the bit monitoring possible time base
errors: STAT:QUES:ENAB 1024.
